CONE-LOCK FOR BALL-BEARINGS.

SPECIFICATION forming part of Letters Patent No. 630,913, dated August15, 1899.

Serial No. 714,601. No model.)

To all whom, (it 777/(bZ/ concern.-

Be it known that LFREDERICK MYERs,a citi- Zen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Cone-Locksfor Ball- Bearings; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

My present invention relates to cone-locks for ball-bearings designedfor use on cycles, vehicles, or railway rolling-stock.

One object of my invention is to provide a simple and efficient meansfor locking the ball-cone on a shaft at any point to which it may havebeen previously adjusted.

Heretofore much difficulty has been experienced in the use ofball-bearing cones on cycles, particularly as at present constructed,owing to fact that the lock-nuts which clamp the cone in place on theaxle and the axle to the fork are liable to work loose at any time andlead to serious breakage or accident.

Another object of my invention is to provide a lock for holding the conein adjusted position on the axle in a reliable and positive manner andnot be dependent entirely upon the uncertainty of screw-threads orjoint-nuts.

By the use of my invention the cone may be adjusted to any position'onthe axle and locked there beyond all possibility of turning, even thoughthe nuts which hold the axle to the fork should become slack.

It is often found necessary to remove a wheel from a bicycle to makerepairs, and the removal of the wheel generally disarranges theadjustment of the cones. Bythe use of my invention this difficulty isobviated, as the removal of the wheel does not change the adjustment ofthe cones.

Various means may be resorted to for securing the cone to thelocking-disk, and I have shown in the accompanying drawings oneconstruction which serves the purpose in a preferable manner.

In the drawings which form a part of this specification, Figure 1 is aside view of a portion of an axle having a cone locked thereon by mycone-lock. Fig. 2 is a face View of my cone-lock. Fig. 3 is a verticalsection of the cone. Fig. 4 is a face view thereof. Fig. 5 is a verticalcentral section through a lockingdisk of a modified form. Fig. 6 is aperspective View of the axle, showing the flattened end portion andbroken away near said end.

Like figures of reference indicate like parts wherever they occur in thevarious views of the drawings.

An ordinary axle is designated by the numeral l.

The ball-cone 2 which I use is provided with a pin or stud 3, projectingoutward from its front or outer face. This cone may be otherwise ofordinary or well-known construction and may be adjusted upon the axle inthe usual manner, as by turning upon the threaded end of the axle, thecone having a threaded bore 4 for such adjustment.

The locking-disk 5 consists of a flat metal plate or disk having acentral aperture 6 and a series of perforations 7, extending entirelythrough the disk near its outer edge or periphery, and theseperforations are located as closely together as possible, and the seriesextends entirely around the disk, as shown in Fig. 2. It will be noticedthat the aperture 6 in the center of the disk has a plane portion 8. Theaxles of bicycles are usually provided with plane or flattened ends inorder that they may be secured firmly against revolving in the slottedends of the fork. The aperture 6 in the locking-disk 5 iscorrespondingly formed in order that it may slide upon the end of theaxle and lie closely up against the cone when the latter has beenproperly adjusted.

The pin or stud 3 on the outer face of the cone is of a size to nicelyfit in any of the perforations 7 of the locking-disk 5 and is located atthe requisite distance from the periphery of the cone to register withany one of the perforations 7.

It will be obvious that I may form a stud or pin 9, Fig. 5, on the disk5 and a series of sockets or perforations in the face of the Y cone andmy purpose would be equally as well served; but I prefer theconstruction previously described.

When it is desired to lock the cone 2 in place upon an axle, it is firstadjusted relatively to the ball-race by turning it upon the threads ofthe axle. WVhen proper adjustment has been effected, the locking-disk 5is slipped on over the axle end and pushed up against the face of thecone 2. The pin 3 on the cone projects through any one of theperforations 7 in the locking-disk 5, and when the nut 10 is tightenedthe parts are held firmly in place and neither the cone nor lock will bepermitted to rotate. Even should the nut 10 become loose the cone anddisk would be held in place so long as the pin 3 remained in theperforation.

It will be obvious that the cone and disk maybe locked together by meansof notches in the periphery of the disk and a pin or projection on theface or edge of the cone, or vice versa.

Vithout desiring to be limited to the exact. construction shown, as I amaware that many changes may be made in the details of my inventionwithout departing from the spirit and scope of the same,

What I desire to secure by Letters Patent and claim is- A cone-lock forball-bearings, consisting of a threaded axle having a flattened end por=tion, a ball-cone having a threaded bore to fit the axle and adapted tobe adjusted there on, an integral pin projecting from the outer face ofsaid ball-cone, and a locking-disk
